No, from 80 years.
Yes, the muon is a subatomic elementary particle. The subatomic label is not really needed; all elementary particles are subatomic.
no, a molecule is composed of 2 or more atoms.
an electron is found in shells , it is a subatomic particle
Subatomic particles are proton, neutron, electron; these particle are some examples of the large group of elementary particles.
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.

The two subatomic particles are protons and electrons. They match the atomic number on periodic table.
The total number of subatomic particles in the nucleus
The number of neutrons is different for isotopes.
This particle is the proton.
The element that an atom is is determined by the number of protons. The number of electrons can be changed (creating an ion), and the number of neutrons can be changed (creating an isotope), and as long as the number of protons does not change, the element that the atom is does not change.
Number of protons in the nucleus is the atomic number.
Subatomic particles with no charges are neutrons
All subatomic particles have mass.
An atom contain protons, neutrons and electrons. The number of these particles is different for each isotope.
